+description: 夸克网盘自动签到。支持通过 URL 参数执行每日签到获取容量奖励，零外部依赖（Python 标准库即可运行）。
+---
+
+# 夸克网盘签到
+
+自动执行夸克网盘每日签到，获取容量奖励。
+
+## 触发场景
+
+- 用户提到「夸克签到」「夸克网盘签到」「签到」且上下文明确指向夸克网盘
+- 用户要求配置夸克网盘自动签到
+
+## 前置要求
+
+- Python 3.7+（已预装）
+- 夸克网盘签到 URL（从夸克 App 或网页获取）
+
+## 获取签到 URL
+
+1. 打开夸克网盘 App 或网页版
+2. 进入「容量管理」或「签到」页面
+3. 浏览器开发者工具 → Network → 找到类似 `growth/sign` 或 `growth/reward_record` 的请求
+4. 复制完整 URL（包含 `kps`、`sign`、`vcode` 参数）
+
+URL 格式示例：
+```
+https://drive-m.quark.cn/1/clouddrive/capacity/growth/reward_record?kps=xxx&sign=yyy&vcode=zzz
+```
+
+## 使用方式
+
+### 方式一：直接运行（推荐）
+
+如果 skill 目录下已配置了默认 `config.json`，无需任何参数即可运行：
+
+```bash
+python scripts/quark_sign.py
+```
+
+### 方式二：直接传 URL
+
+```bash
+python scripts/quark_sign.py --url "你的完整URL"
+```
+
+### 方式三：配置文件
+
+```bash
+# 1. 复制示例配置并编辑
+cp config.json.example ~/.config/quark_sign.json
+# 填入你的 URL
+
+# 2. 运行
+python scripts/quark_sign.py --config ~/.config/quark_sign.json
+```
+
+### 方式四：环境变量
+
+```bash
+export QUARK_SIGN_URL="你的完整URL"
+python scripts/quark_sign.py
+```
+
+## 常用命令
+
+```bash
+# 执行签到
+python scripts/quark_sign.py --url "URL"
+
+# 仅检查今日是否已签到
+python scripts/quark_sign.py --url "URL" --check
+
+# 查看签到信息
+python scripts/quark_sign.py --url "URL" --info
+```
+
+## 输出示例
+
+```
+🚀 执行签到...
+✅ 签到成功！获得 100.00 MB
+```
+
+```
+🚀 执行签到...
+ℹ️ 今日已签到过，无需重复签到
+```
+
+## 默认配置
+
+skill 目录下已内置 `config.json`，作为默认 URL 来源。URL 查找优先级：
+
+1. `--url` 参数
+2. `--config` 指定的配置文件
+3. 环境变量 `QUARK_SIGN_URL`
+4. skill 内置 `config.json`（默认使用）
+
+## 注意事项
+
+- URL 中的 `kps` 和 `sign` 参数有有效期，如失效需重新获取
+- 签到奖励通常为 100MB~1GB 不等，随机发放
+- 脚本支持 `requests` 库（如已安装）或纯 Python 标准库（零依赖）
+- 默认配置适合个人使用，多用户场景建议各自使用 `--config` 或 `--url`
+
+## 配置 cron 定时任务
+
+```bash
+# 每天 9 点自动签到
+crontab -e
+# 添加：
+0 9 * * * python3 /path/to/quark-sign-skill/scripts/quark_sign.py --config /root/.config/quark_sign.json >> /var/log/quark_sign.log 2>&1
+```

-# Adding a New LLM Provider (packages/ai)
-
-A new provider touches multiple files. Work through these steps in order.
-
-## 1. Core Types (`packages/ai/src/types.ts`)
-
-- Add API identifier to `Api` type union (e.g. `"bedrock-converse-stream"`).
-- Create options interface extending `StreamOptions`.
-- Add mapping to `ApiOptionsMap`.
-- Add provider name to `KnownProvider` type union.
-
-## 2. Provider Implementation (`packages/ai/src/providers/`)
-
-Create a provider file exporting:
-
-- `stream<Provider>()` returning `AssistantMessageEventStream`.
-- `streamSimple<Provider>()` for `SimpleStreamOptions` mapping.
-- Provider-specific options interface.
-- Message/tool conversion functions.
-- Response parsing that emits standardized events (`text`, `tool_call`, `thinking`, `usage`, `stop`).
-
-## 3. Provider Exports and Lazy Registration
-
-- Add a package subpath export in `packages/ai/package.json` pointing at `./dist/providers/<provider>.js`.
-- Add `export type` re-exports in `packages/ai/src/index.ts` for provider option types that should remain available from the root entry.
-- Register the provider in `packages/ai/src/providers/register-builtins.ts` via lazy loader wrappers; do not statically import provider implementation modules there.
-- Add credential detection in `packages/ai/src/env-api-keys.ts`.
-
-## 4. Model Generation (`packages/ai/scripts/generate-models.ts`)
-
-- Add logic to fetch/parse models from the provider source.
-- Map to the standardized `Model` interface.
-
-## 5. Tests (`packages/ai/test/`)
-
-- Always add the provider to `stream.test.ts` with at least one representative model, even if it reuses an existing API impl such as `openai-completions`.
-- Add the provider to the broader matrix where applicable: `tokens.test.ts`, `abort.test.ts`, `empty.test.ts`, `context-overflow.test.ts`, `unicode-surrogate.test.ts`, `tool-call-without-result.test.ts`, `image-tool-result.test.ts`, `total-tokens.test.ts`, `cross-provider-handoff.test.ts`.
-- For `cross-provider-handoff.test.ts`, add at least one provider/model pair. If the provider exposes multiple model families (e.g. GPT and Claude), add at least one pair per family.
-- For non-standard auth, create a utility (e.g. `bedrock-utils.ts`) with credential detection.
-
-## 6. Coding Agent (`packages/coding-agent/`)
-
-- `src/core/model-resolver.ts`: add default model ID to `defaultModelPerProvider`.
-- `src/core/provider-display-names.ts`: add API-key login display name so `/login` and related UI show the provider for built-in API-key auth.
-- `src/cli/args.ts`: add env var documentation.
-- `README.md`: add provider setup instructions.
-- `docs/providers.md`: add setup instructions, env var, and `auth.json` key.
-
-## 7. Documentation
-
-- `packages/ai/README.md`: add to providers table, document options/auth, add env vars.
-- `packages/ai/CHANGELOG.md`: add entry under `## [Unreleased]`.
